So far it has been known that ordinary matter makes up only 5% of the universe or whatever we know. But almost half of this percentage still remains unknown. Now a new study has shown that majority of the missing ordinary matter is found in the form of a very hot gas associated with intergalactic filaments.

The team led by a researcher from University of Geneva (UNIGE), Switzerland, claims that they observed the phenomenon directly. The study’s findings have showed that the majority of the undetected ordinary matter is found in the form of immensely hot gases that are associated with intergalactic filaments.

According to researchers whose findings were published in the journal Nature, galaxies are formed when an ordinary matter collides and then gets cooled.

Furthermore, in order to better understand the formation of galaxies, researchers said it was very important to discover where and in which form ordinary matter exists.

For this, researchers studied Abell 2744, a massive cluster of galaxies with a complex distribution of dark and luminous matter at its center, using the XMM space telescope.

The astrophysicists pointed XMM in the direction of the areas where they suspected to find the presence of filaments. For the first time ever, they were successful in measuring the temperature and density of these objects.

Dominique Eckert, lead author of the study, said their study is a very significant validation of the models of galaxy formation in the universe.
